Water Level
2013-12-19	20010375	CS451	Installed	Water Level	Installed on the East End tower. From field note calculations, sensor was installed 82cm below ground level. Top of the pipe to ground = 53 cm Water level was at ground surface Well pressure: 1.17 psi ~ 82 cm
2014-04-03	20010375	CS451	Moved	Water Level	Moved up 93.6 cm (sensor changed from 2.06 psi to 0.73 psi)
2015-01-05	20010375	CS451	Removed	Water Level	Removed from the site due to the tower falling over in the wind on 2014-12-30. Likely undamaged.
2015-01-20	20010375	CS451	Installed	Water Level	Reinstalled after being removed when the scaffolding fell over. Installed at 88cm below ground level. Water level was 8cm agl.
2018-09-18	20010375	CS451	Moved	Water Level	Position adjusted when troubleshooting. From field notes: Top of pipe to sensor = 66 cm Top of pipe to water = 30 cm Sensor depth under water should be 66-30=36cm Sensor = 0.66psi ~ 46 cm
2020-07-21	20010375	CS451	Removed	Water Level	Removed from EE and brought back to the lab to repair a chewed section of the cable.
2020-08-05	70011229	CS451	Installed	Water Level	Installed at EE to replace sn 20010375, which was brought back to the lab for repair. From field note calculations, sensor was installed 22cm below ground level. Top of well to ground level= 41 cm Top of well to sensor = 63 cm Top of well to bottom of well inside pipe = 66 cm (dry at bottom of well)
